What is systems thinking and practice? The essence of systems thinking and practice is in 'seeing' the world in a particular way because how you 'see' things affects the way you approach situations or undertake specific tasks. This free course will help you to learn about the problems of defining a system and meet some of the key concepts used in systems theory: boundary environment positive and negative feedback

This micrograph is of a specimen which has been pressed from either side during fabrication, with the bright graphite flakes appearing edge on. Compare with micrograph 194.The MgO grain is polycrystalline and porous. The anisometric microstructure means the brick properties are anisotropic and so the bricks orientation must be carefully controlled on installation. These are true composite materials using ceramic (MgO, natural graphite), metal (Si, Al additives), and polymer (phenolic resin) components.

There are a wide range of interactions between 'science' and 'the public'. Examples range from visiting a museum or indulging in a science-related hobby to reading a newspaper article about a breakthrough in the techniques of therapeutic cloning. Many of these interactions could be said to be 'passive'. This free course explores the practicalities of the public becoming more 'active' in the direction of science practice by 'two-way' interactions

This is an example of a quenched and tempered steel. The steel is initially quenched from the austenite phase field to form hard and brittle martensite. Subsequently the steel is reheated to allow diffusion of the interstitially trapped carbon and hence reduction of the lattice strain. This results in a softer and tougher steel.

The colours in the image are the result of birefringence and relate to the strain-induced alignment of the polycarbonate molecules. Because the specimen is below the glass transition temperature of PC (145 Ā°C), the material will relax when the stress is removed and there will be no residual alignment. The colours reveal the pattern of stress concentration around the points of contact with the rig, with a neutral axis along the centre and opposite values of birefringence on either side.
